A linear model for inertial modes in a differentially rotating Sun
Jishnu Bhattacharya, Chris S. Hanson, Shravan M. Hanasoge +1
Inertial wave modes in the Sun are of interest owing to their potential to reveal new insight into the solar interior. These predominantly retrograde-propagating modes in the solar…
A spectral solver for solar inertial waves
Jishnu Bhattacharya, Shravan M. Hanasoge
Inertial waves, which are dominantly driven by the Coriolis force, likely play an important role in solar dynamics, and additionally, provide a window into the solar subsurface. Th…
Numerical evaluation of time-distance helioseismic sensitivity kernels in spherical geometry
Jishnu Bhattacharya
Context: Helioseismic analysis of large-scale flows and structural inhomogeneities in the Sun requires the computation of sensitivity kernels that account for the spherical geometr…
Helioseismic finite-frequency sensitivity kernels for flows in spherical geometry including systematic effects
Jishnu Bhattacharya
Helioseismic inferences of large-scale flows in the solar interior necessitate accounting for the curvature of the Sun, both in interpreting systematic trends introduced in measure…
A general formulation for computing spherical helioseismic sensitivity kernels while incorporating systematical effects
Jishnu Bhattacharya, Shravan M. Hanasoge, Katepalli R. Sreenivasan
As helioseismology matures and turns into a precision science, modeling finite-frequency, geometric and systematical effects is becoming increasingly important. Here we introduce a…
Validating time-distance helioseismic inversions for non-separable subsurface profiles of an average supergranule
Vedant Dhruv, Jishnu Bhattacharya, Shravan Hanasoge
Supergranules are divergent 30-Mm sized cellular flows observed everywhere at the solar photosphere. Their place in the hierarchy of convective structures and their origin remain p…
